Shield Bubble(20 credits each, sometimes issued free by some governments) shield bubbles are citizen-grade emergency protection units. A shield bubble is activated by pulling a tab which expands the device into a large plastic bubble that a person has one minute to enter before it hardens. During this time multiple bubbles may be joined to make a small complex. Natural filters provide clean, breathable air while the tough shell grants +1 to the AC of those inside and is durable enough to withstand 10 points of damage before breaking. Shield bubbles are often carried by individuals in dangerous territory or during military or civil unrest.
